okay, so i've done the maths...
just for comparative purposes i threw this chart together to quantify the savings from the new rent rates. all figures are based on current mining lease boundaries, so obviously this will change as projects advance and new ml's are applied for.
perhaps the apc number is most indicative as they are clearly the most advanced in terms of ml application and grant. $2.3m over 5 years a pretty good saving and will reflect directly on the bottom line imo.
